Adds factory buildings you can walk into and build parts of your factory inside. This mod will not be updated for Factorio 0.15! Get Factorissimo2 instead, it's much better.
Here are recipe changes to make the mod less op. Now it wont be as cheap as before.

Edit: Made the recipe even more expensive.
Edit2: Hm maybe I should add lights too.
